Scientists Use “Big Bang” Supercomputer to Build Better Jet Engine


Injectors atomize liquid jet fuel and spray it into the combustion chamber where it burns and generates energy for propulsion. “They are one of the most challenging parts to design and very expensive to produce,” Madhu Pai, an engineer in the Computational Combustion Lab at GE Global Research, says. (The next-generation LEAP jet engine is the world’s first engine with 3D-printed injectors.)


This is physics with practical implications. Pai says that small changes to fuel nozzle geometry could lead to significant changes in engine performance. “These high-fidelity computer simulations help us understand how air and fuel mix and burn, and eventually reduce the number of trials. Ultimately, we want to build more powerful engines that consume less fuel and have lower emissions.” more> http://tinyurl.com/mcfr5o9
